.default-example {
  font-size: 1.2rem;
}

#example-element {
  width: 100%;
  background: #be094b;
  color: white;
}

section {
  text-align: left;
  flex-direction: column;
}

hr {
  width: 50%;
  color: lightgray;
  margin: 0.5em;
}

.note {
  font-size: 0.8rem;
}

.note a {
  color: #009e5f;
}

@counter-style space-counter {
  symbols: "\1F680" "\1F6F8" "\1F6F0" "\1F52D";
  suffix: " ";
}

The color of the marker will be the same as the computed color of the element it applies to.

只有几个元素 (<li> 和 <summary>) 的默认值为 display: list-item。但是， list-style-type 属性可以应用在任何 display 的值为 list-item 的元素上。此外，由于这个属性是可继承的，它可以设置在父元素上 (通常是 <ol> 或 <ul>) 以便应用于所有子元素 (<li>)。

Accessibility concerns

The VoiceOver screen reader has an issue where unordered lists with a list-style-typevalue of none applied to them will not be announced as a list. To address this, add a zero-width space as pseudo content before each list item to ensure the list is announced properly. This ensures the design is unaffected by the bug fix and that list items are not improperly described.

ul {
  list-style: none;
}

ul li::before {
  content: "\200B";
}

注释

• Some types require a suitable font installed to display as expected.
• The cjk-ideographic is identical to trad-chinese-informal; it exists for legacy reasons.
